sooo, i decided to just bite the bullet and I purchased a set of aftermarket rims and some performance snow tires. i didn't want to waste my time looking for used X3 rims with all weather tires. at least these are brand new and are rated for the autobahn when it's nice out.

my question is about the TPMS. i had the TPMS sensors installed by tire rack, but is there an activation process or is there anything i have to do/setup for the BMW system to recognize whatever system was installed by tirerack? is this like a bluetooth function or will the BMW system just recongnize the new/different sensors?

i did a search and there were some topics on TPMS, but nothing really answered the question i have.
